Battery charge notice

It is important to consider the environment temperature whenever the Lithium-Ion battery pack

is charged. Charging is most efficient at normal room temperature or in a slightly cooler

environment. It is essential that batteries are charged within the stated range of 10°C to 45°C.

Charging batteries outside of the specified range could damage the batteries and shorten their

charging life cycle.

CAUTION! Do not charge batteries at a temperature lower than 0°C, which will increase the

internal resistance to cause heat and make the batteries unstable and unsafe.

Please use a battery temperature detecting device for a charger to ensure a safe

charging temperature range. Further, to protect and avoid battery from inflating, the

battery is detected for thermal protection and will not be charged when the

temperature of battery is over 50 degrees.

Do not leave the terminal for a long time in the charging cradle and do not charge

the battery with a cable long, which will shorten the battery life and cause battery

expanding/ballooning. The unit should not be subject to very high temperature,

excessive moisture, and direct heat. Avoid the battery from being fully charged and

staying in a high temperature environment. Avoid terminal or spare battery from

staying in a hot vehicle. For prolonging the storage time, keep the battery at a 40%

charge level. Lithium ion batteries oxidize least when they are stored at the state of

40% charge.

Storage and safety notice

Although charged Lithium-Ion batteries may be left unused for several months, their capacity

may be depleted due to build up of internal resistance. If this happens they will require

recharging prior to use. Lithium-Ion batteries may be stored at temperatures between -25°C to

60°C, however they may deplete more rapidly at the higher temperature ranges. It is

recommended to store batteries within normal room temperature ranges.
